USDA Plant Hardiness Zones

To help gardeners understand which plants will grow well for them, the entire USA has been segmented into ‘Plant Hardiness Zones’. Knowing your zone number is helpful when shopping for plants because:

  • Cold-area gardeners can avoid buying plants that simply won’t survive their lowest winter temperatures.
  • Warm-area gardeners can steer clear of plants that need a period of cold weather in order to bloom again.

Plant Information

The evening primroses are a group of yellow-flowered plants that range from short “sundrops” to the tall ones like this species. Unlike the roadside weed, Oenothera biennis, O. lamarckiana makes a good meadow plant. Flowers open in the afternoon and are closed by morning. See related species—the ground-hugging, very large-flowered Missouri Primrose, O. missouriensis and the famous pink-flowered Showy Evening Primrose, O. speciosa.

    Comments about American Meadows Evening Primrose Seeds:

    When this plant first came up this spring, I thought it might be a weed. I decided to wait and see what it looked. So glad I did. The yellow flowers on the branches open up in the evening and almost glow on a night with a full moon. I really enjoyed watching it grow and bloom. Now that it is August and the bloom time is nearing its end, seeds are being produced. The plant is full of gold finches that look almost like large blooms. I had to do a double take. I am hoping the goldfinches spread the seed far and wide for more beautiful plants in my area. There are huge natural areas near my house because I live near a park.

        Comments about American Meadows Evening Primrose Seeds:

        Planted seeds 2 years ago along our pond embankment and in a wilflower bed near our patio with great success. Plants continue to reseed themselves to the delight of our grandchildren who enjoy watching the blossoms open as the late afternoon sun melds to twilight. Would make an excellent plant for patio containers as well.

        Q & A

        Plant With These:

        USDA Hardiness Planting Zones

        To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.

        • If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
        • If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
